PULLING MACI-IENE.

Application filed. August 13, 1825. Serial No. 50,042.

ratus to which our invention is particularly applicable.

Gur invention resides more particularly in the provision of means whereby a tractor provided with winch or winding drun. may be conveniently and effectively employed in connection with'the mast of a pulling apparatus, and has for one of its objects the provision of means whereby the pulling mast structure and the tractor may be braced, one by the other, during a pulling operation and wherein a workman may not be 1n ured by coming between the trac' tor and the mast as sometimes happens in present practice.

One form which our invention may take is shown in the accompanying drawing wherein Fig. 1 is a view, in side elevation, of apparatus embodying our invention; Fig. 1?. tion of the apparatus of Fig. 1, and Fig. 3 is a view, on an enlarged scale, of an at taching bracket by means of which the apparatus may be connected to the pulling mast structure.

In the course of development of the art, tractors were substituted for horses in pulling tubes and pump rods'o't' oil wells, masts similar to that shown in the drawing being employed and provided with guiding sheaves or pulleys around which a cable passed, one end of the cable being hitched to therod or tube being pulled, and the other end to harness traces. The tractors usually come equipped with a winch or winding drum and have commonly been anchored to a tree or a stake. The pulling rope or cable that extends over the mast pulley is wound on the winch. Frequently the tract-or breaks loose from its anchorage and may hit the mast with such force as to break the same. Furthermore, workmen have been sometimes injured through being present between the tractor and the mast at times when the tractor breaks loose.

In the accompanying drawing we have shown a tractor t which is provided with a power shaft that may be of the usual form is a rear elevational view of a por-,

found-on many tractors and be mounted either the rear end orthe front of the tractor. The shaft 5 is provided with a pinion (3 that meshes with a gear wheel 7 oi? a winding drum or winch. The gear wheel 7 is mounted in bearings that are supported from the tractor l by means of rackets 8. I

The mast is shown as having a framework composed of horizontal channel irons 9 and vertical channels 10, for supporting the mast sections 11 and 12. The shaft is provided with a sheave 13 over whichpasses a ropeor cable in One end 01" the cable is connected to'the tubing or pump rods of a well 15 when it is desired to pull the same, and the other end is connected to the winding drum or winch above referred to.

To each of the channel members 10 we bolt a bracket member 16. A brace member 17 is bolted at its upper end to the bracket 16 and at its lower end to the mast frame.

During the operation of the device, the tractor is positioned against the bracket. members 16 so that both the tractor and the mast will be braced, by reason of their abutting engagement with one another, against movement. It is desirable, however, that means he provided for preventing displacement of the tractor and the mast frame and for this purpose we employ, at each side of the tractor, a metal bar or strap 18 whose lower end is provided with a hole through which a bolt 19 may extend, for the purpose of securing said bar to the tractor. The bolt 19 may replace the usual shorter bolt by which the bearing for the gear wheel 7 is secured to the tractor i'rame. Washers or spacers 20 may be conveniently employed, although he lower end of the bar 18 may be so bent to render such spacers unnecessary.

The upper ends of the bars 18 are provided with either a slot 21 as shown, or with a plurality of holes, by means or" which they may be adjustably 16. Bolts 22' extend through the brackets 16 and the slots 21. This arrangement permits the tractor to be readily secured to the mast even though the tractor and the mast frame are not in perfect alignment, as when the surface of the ground is uneven.

It will be seen that the tractor and the mast require no other means for holding them against relative movement in a horisecured to the brackets Ill) zontal direction, and that itis impossible for a workman to walk between them.

lVe claim as our invention r 1. The combination with a mast structure provided with frame members extending in a vertical direction at its sides, and atractor provided with a horizontally disposed winch shaft, of means for connecting said winch member at each of its ends to said side frame members, comprising a bar secured to said winch at each end thereof and to one of said side frame members. 2. The combination with a mast structure adapted for use in pulling tubing and the like, and a tractor provided with a winclrsupporting frame, of a bracket connected to said mast, and means for connecting said winch frame to said bracket, comprising a bar secured to said frame at each end thereof and a vertically adjustable connection between one of said bars and said bracket. p

3. The combination with a mast structure adapted for, handling tubing and the like, and a tractor provided with a winch having an axle disposed in a horizontal plane, of a bearing adjacentto each end of said axle, and laterally spaced bracket members connected to said mast structure and each having engagement with one of said bearg I 4. The combination with a mast structure adapted for handling tubing and the like, and a tractor provided with a winch having an'aXle disposed in a horizontal plane, of a bearing adjacent to each end of said axle, and laterally spaced bracket members connected'to said mast structure and each hav-. ingadjustable connection with one of said bearings.

In testimony whereof we, the said Room P. STEELE and JOHN DWYERhave hereunto set our hands.
